a Molecular structure of Schiff bases (1-F, 1-Cl, and 1-Br). b, c Ferroelastically deformed crystal of 1-Cl under polarized white light and UV light, respectively. αM and αD correspond to mother and daughter domains in ferroelastically deformed crystals, respectively. d Surface roughness of mother and daughter domain of ferroelastically deformed crystal of 1-Cl. e Snapshots of 1-Cl crystal during the stress-displacement measurements. f–h Stress-displacement curves of a single crystal of 1-F, 1-Cl, and 1-Br, respectively. i Coercive and reverse stress of ferroelastic deformation of 1-F, 1-Cl, and 1-Br, and (j, k) elastic moduli of 1-F, 1-Cl, and 1-Br. The forward stress, reverse stress, and elastic modulus values are expressed as mean ± standard deviation, n = 3.
